Skull Duggery is a video slot machine developed by Microgaming on its Viper platform. As its name suggests, the theme of the game is pirates. The emphasis is on pirate booty, and the game boasts a distinct Caribbean flavor. Skull Duggery features five spinning reels and nine paylines. Coin sizes range from £0.01 to £5, and the player can choose how many paylines are active each spin. The minimum bet is just £0.01, the minimum bet to activate all lines is £0.09 and the maximum stake is £45.


The Skull Duggery symbol set includes 11 unique items: coconuts, bananas, nectarines, grapes, oranges, tankards of ale, buried treasure maps, the captain, robbers, a skull and the Skull Duggery logo. The main menu is at the bottom of the play area. The plus and minus buttons adjust the coin size. The Select Lines button cycles through one to nine active paylines. The Select Coins button cycles through one to five coins per line in play. The Spin button starts the round. Alternatively, the Bet Max button will configure the maximum wager and then start the round.

Special Features

Skull Duggery offers several special features: a wild symbol, a scatter symbol and a second-screen bonus game. The Skull Duggery logo is both the jackpot symbol and the wild symbol. As a wild, it can substitute for any symbol besides the robbers and the skull. The skull is a scatter symbol, and it pays out whenever two or more hit on active paylines, anywhere on the reels.

The robbers serve as the bonus symbol and will launch the bonus game when three or more appear on active paylines, anywhere on the reels. The bonus is a simple game that has the player pick one of several options to reveal a prize. The bonus always awards something, and the maximum prize possible depends on the number of robbers that triggered the event: three robbers allows for 40-750 coins, four allows for 100-1,500 coins and five allows for 200-3,000 coins.

Graphics and Audio

Skull Duggery uses a 2D style that is fittingly cartoonish and has animations on the reels. The game doesn’t have any music, and the selection of sound effects, while good, is rather limited.


Skull Duggery offers two non-progressive jackpots: the bonus jackpot and the standard jackpot. At the maximum possible, the bonus is worth 3,000 coins, or £15,000 at the max coin size. The standard jackpot, on the other hand, is worth 12,000 coins, which amounts to £60,000 at the max coin size.


Skull Duggery is a straightforward, fast-paced slot game that has a fun, lighthearted style. Since the payout table doesn’t scale evenly and significant prizes are awarded via the bonus, Skull Duggery is best played by committing to the largest per-spin stake that the player’s bankroll supports.
